GOVERNOR-VALVE.

v SPECIFICATION forming part of Letters Patent No. 590,281, datedSeptember 21, 1897'.

Application filed March 2 0,1897' T0 all whom t may concern.-

Be it known that l, JAMES N. BUNDLE, a citizen of the United States ofAmerica, residing at Santa Barbara, in the county of Santa Barbara andState of California, have invented certain new and useful Improvementsin Governor-Valves, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to improvements in governor-valves forsteam-engines, and more' particularly to that class of governors whichare interposed in a steam-pipe between the boiler and the engine,thereby controlling the flow of the steam and consequently regulatingthe speed of the engine. To accomplish this purpose I have constructed avalve simple in its construction, effective in its operation, and onewhich will perform all of its intended functions.

With these objects in view my invention consists in the particu-larconstruction of the various parts and in the novel manner of combiningor arranging said parts, all of which will be described hereinafter, andpointed out in the claims.

In the drawings forming part of this speciiication, Figure 1 is avertical sectional view showing all the parts in place. Fig. 2 is adetail perspective view of the supporting mechanism and valve-seat. Fig.3 is a side elevation of the valve-supporting mechanism, showing theadjustable screw for regulating the fulcrum-block.

Referring to the drawings, A designates the steam-pipe leading from aboiler and opening into the head of the valve. y

B designates the steam-pipe leading from the valve to theengine-cylinder.

C designates the valve-casing,consisting of any suitable material andconstruction, of such dimensions as to support within itself theInechanism of my device. The top cover 2 is suitably fitted and screwedto the cylinder by threaded flanges 3 and formed with a pipe extension4, which is connected in any desirable manner to the pipe A. The bottom5 of the said cylinder is formed with a central iiange-apcrture G,having interior screwthreads, as shown in Fig. 1 of the drawings.

The upper end of the steam-pipe B opens Vopening 10 in the valve-seat 7.

into the valve-casing C and is fitted with a Serial No. 628,472. (Nomodel.)

sliding valve-seat 7, consisting of a tubular sleeve or body formed witha right-angular fiange 8 at its upper end, which rests on the saidsleeve in position. In the bottom of the said casing is secured a bench9, in the center of which is secured an inverted cone orV conical valve10, registering with the valve- On the upper face of said bench 9 issecured a pin-point bearing 11, on which the governor-spindle ismounted.

Ddesignates the governor, which is composed of a shaft or spindle 1'2,having its lower end formed with a socket to lit over the pinpointbearing, said shaft carrying a springgovernor composed of two collars 13and 13', connected by spring-bars 14 and 14. The upper head-piece 13 ismade fast to the spindle in any desirable manner, and the lowerhead-piece or collar 13 is free or loose on the said spindle, so thatwhen the governor rotates the weights 15 and 15 on the said springarmswill move outward, and the collar 13 will thus be drawn upward on thespindle, and the valve below will also be correspondingly affected andactuated, as hereinafter more fully specied. 0n the upper end of thegovernor-spindle is formed or carried a spiral 16, which extendsupwardly into the pipe 4. It is by this spiral that the governor isrotated. The pitch or turn of the said spiral may be suited to the sizeof the pipe in which it is fitted and also to give the desired velocity.

E designates the mechanism for controlling and actuating the valve, andreferring to Fig. 2 of the drawings it will be seen that on the end ofthe bench 9 is a sliding fulcrum 17. Said fulcrum is adj ustably mountedbeneath the valve lever or yoke and is regulated by means of a set screw18, which extends through the wall or casing of the said cylinder andhaving its end suitably connected to the said fulcrum, on which issupported a frame or yoke substantially in a horizontal positionandcarrying on its end nearest the set-screw a weight 2l, which isintended to couuterbalance the weight of the said frame or yoke. It willbe seen that by moving the fulcrum away from or toward the axis of thegov- Vbottom of the valve-casing and supports the IOO ernor the weightis made to assume greater the yoke connected to the valve-seat shortenedor lengthened. Thus the valve-seat is correspondingly effected.

On opposite sides of the valve-seat are secured lugs 22 and 22", towhich the lower ends ofthe links 23 and 23 are pivotally connected,theupper end of the link being pivotally connected to the arms of ltheyoke 20, as shown in thedrawings.

To keep the arms of the yoke from spreading, a brace or keeper 24 may besecured across them. In the bars of the yoke 2O are securedoppositely-disposed lugs or pins 25 and 25', which engage an angulargroove 26 in the lower head-piece 13', whereby the yoke is lowered orraised and the valve moved away from or toward the valve-seat.

The operation of my improved valve-governor is asfollows: The steamrushes through the pipe and engages the spiral, thus rotating thegovernor. spring-arms of the governor move outward, thus shortening anddrawing the yoke upward by its connection therewith, the yoke in turnraising the valve-seat, thus diminishing the flow of the steam to theengine. Then as the governor tends to resume its normal velocity thevalve-seat is lowered and the steam,- increased. Thus the mechanism whenproperly adjusted acts to control the speed in the same manner as a.governor used on a rotary engine.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination with the steam-pipes A and B,y a suitable casing Cinterposed between said pipes, a shaft journaled in said casingYprovided with a governor, and a' spiral, of-v a valve in the bottom ofthe casing and yoke mounted upon a fulcrum said yoke connected to thevalve-seat, and to the free head As the speed increases the or collar ofthe governor, substantially as shown and described.

2. In a valve-governor the combination with a steam-pipe, of a casinginterposed therein, a shaft journaled in said casing having a governormounted thereon and lts upper portion provided with a spiral groovesaid` spiral extending up into the inletLpipe, a valve in the bottom ofthe casing, and a yoke fulcrumed in said casing connected to thevalve-seat and to the free head or collar of the governor, a weight onsaid yoke, substantially'as shown and described.

3. The combination 'with the steam-pipe of a casing interposed therein,a shaft mounted in saidA casing, said shaft provided with weightedgovernor-springs and a spiral groove secured upon theupper end of theshaft, and extending into thesaid steam-pipe, a valve in the bottom ofthe casing7 a yoke adjustably fulcrumed in the said casing connected tothe valve and governor, and a screw toadper end extending from thecasing into the steam-pipe, a valve in the bottom of thesaid 'casingprovided with a sleeve projecting into the discharge-pipe, andconnections between v the said valve and governor, whereby they valve isopened and closed, substantially asV shown and for the purpose setforth.

In testimony whereof I have affixed my sig nature in presence of twowitnesses.
